ATTORNEYS United States Patent 2,719,7 51 LIQUID-DISTRIBUTING DEVICEFingal C. Orr, Glendale, Calif. Application February 16., 1953, SerialNo. 337,135 8 Claims. (Cl. 29969) This invention has to do with devicesfor distributing liquids in circular paths occupying a multiplicityofplanes.

An object of my invention is to provide a novel, liquiddistributingdevice which is actuated by the liquid to causedrawing and the followingdescription. Referring to the drawing:

Fig. 1 is an elevational view of a device embodying the invention;

Fig. 2 is a plan view of the device of Fig. 1;

Fig. 3 is a sectional view on line 3-3 of Fig. 1;

Fig. 4 is a fragmentary elevational view on line 44 of Fig. 2;

Fig. 5 is a fragmentary elevational view of a modified pawl mechanism;and

Fig. 6 is a fragmentary elevational view on line of Fig. 5.

More particularly describing the invention, 11. generally indicates anX-shaped fitting member having a depending central neck 12 internallythreaded at 13 to receive a tube 14. The latter is slidably androtatablymounted within a main fitting 16 in the form of a tubular bodyterminating at its lower end in a threaded portion 17 for attachment toa supply pipe 18. Tube 14 extends through fitting 16 and is fitted witha collar 20 at its lower end to limit upward movement of the tube.

The member 11 rotatably supports a horizontal tubular shaft 22 which isclosed at one end as by plug 23. The shaft is apertured at 22' withinfitting 11 so that it will receive fluid delivered by tube 14. At itsother end there is rigidly mounted a spray head or discharge headassembly, generally indicated by 24, and including a head 25 having aneck 26 attached rigidly to the shaft 22 and having a portion 27 atright angles thereto fitted with a discharge tube or nozzle 28. Themember 25 also carries an actuator member 30 which is mounted on a pin32 which is rotatably mounted in the fitting 25. The actuator member isattached at one end of the pin. The other end of the pin is apertured at33 to receive coil spring 34, one end of which is anchored in anapertured abutment lug 35 on the body 25. The spring serves to bias theactuator member toward and against the lug 35.

The actuator member includes a spoon-shaped deflector end portion 38normally in the path of liquid emerging from nozzle 28 and a laterallydisposed vane 39.

The fitting 11 is provided with a laterally projecting pin 41 which isthreaded into the body. Pivotally mount- 2,71 9,75 l Patented Oct. 4,195.5.-

2 ed on this is a, pawl 42, which hangs by gravity in an inclinedposition. The lower end, of the pawl rests against a serrated track 44of circular shape formed on the upper surface. of a flange, 45 mountedon the fitting 16 The pawl prevents rotation of fitting, 11 and carriedparts in a counterclockwise direction as viewed in Fig. 2,

In the operation of the device liquid delivered by the supply pipe 18passes through tube 14 to the interior of fitting 11 and then entersshaft 22 flowing to fitting 25 and. emerging at a relatively highvelocity throughthe nozzle 28.. The. emerging liquid impinges upon thede-.

flector portion 38 of the actuator member, causing this member to pivotto the left, as. the device is viewed in Fig. 2. In so pivoting, thevane. 39 enters and passes, through the fluid stream serving to, carrythe actuator member to a position such that it occupies substantially.'the broken-line. position shown in Fig. 2 Spring 34 returns theactuator member to the original position- As a result of the forcesinvolved, the head 25 and shaft.

22 rotate about the axis of shaft 22 and at the same, time the assemblycarried by tube 14 is, caused to rotate about the axis of rtube.intermittently due to the reactionary force of liquidiissuing from thenozzle when the parts are. in the. position shown in Fig. 2. Anytendency. of; the discharging fluid to reverse this direction ofrotation of the entire assembly carried by the member 11 is pre: n ed.by Da .4 whic p m t rot n of th afo ementioned assembly clockwise asviewed in Fig, 2 but prevents rotation in the opposite, direction.

While the pawl 42 will operate under the influencev 1 of a y a on I ypro ide a sp n to urge it t r the, flange 45. Thus iniF-igs. 5 an 6. Ishow a pawl 424. car ies o an elonga dvpin 4 hich accommoda e a. coilpri g o e end of hi li a inst the i e of the pawl and the other end ofwhich 'is, mounted in slot 52 in the end, of the pin. The tension of thespring can thus be adjusted. Such a spring can be employed on theconstruction shown in Figs. 1--4.

Where a spring is used a foot 53 of leather or othersuitable materialcan be employed between the end of the pawl and the'flange memberagainst which it works,

the foot being mounted by means of a cotter pin 54 extending throughholes in the parts. Where the foot is used, the flange, here indicatedby 45a, may have a smooth upper surface, friction being relied upon toprevent backward rotation. Also, with this construction, the speed offorward rotation of the tube 14, head 11 and carried parts can beadjusted by adjusting the tension of spring 51.

While I have illustrated preferred forms of my invention, I contemplateanother form thereof which comprises the construction shown in Figs. 1-4without the pawl 42 and flange 45. When the parts 42 and 45 are omittedthe member 11 and connected parts progressively rotate counterclockwise.This is due to the fact that discharge head assembly 24, as it is drivenby the reactionary thrust of the issuing liquid, travels fasterdownwardly than it does upwardly in its rotation about its horizontalaxis with the result that, in each cycle of rotation it has a longertime in which to tend to rotate member 11 and connected parts in acounterclockwise direction than in a clockwise direction, the resultbeing the progressive advance of the moving parts counter clockwiseabout the axis of tube 14.

Although I have shown specific forms of my invention, I contemplate thatvarious changes and modifications can be made without departing from thescope of the invention as indicated by the claims.
